Abstract

PercevalHR (Perceval High Resolution) is an artificially designed fluorescent protein, which changes its excitation spectrum based on the ADP/ATP ratio of the environment. Here we demonstrated that PercevalHR can be used for monitoring energy status of Saccharomyces cerevisiae cells, which are affected by diauxic shift and mitochondria inhibition, in a non-invasive and non-destructive manner.
